Sodium ions and chloride ions are arranged in a repeating pattern, creating a cubic crystal lattice. Option C
Sodium chloride, also known as table salt (NaCl), is not a distinct molecule with a well-defined structure. Rather, it creates an extended three-dimensional structure that resembles a cubic crystal lattice thanks to the repeating pattern of sodium and chloride ions.
One distinctive aspect of sodium chloride's structure is the crystal lattice's cubic form. Thus, "cubic" is the proper phrase to describe the shape of a table salt structure.
